In the heating and ventilating of schoolend. The radiator ma have more, or less, rooms, halls, churches, and the like, with than twelve sections, depending upon the steam radiators, coils in sufficient number service required of it, and the number of seeare used to give radiation which will be ample tions at the end, remaining outside of the box,

Brought thus while those contained within the box 3 are into intimate contact with the major number to warm a supply of air entering the box from of radiator sections, the cool air from outthe outside of the house through a wall box doors is heated before it is discharged into 4. which box 4 discharges into the base 5 the room. of the radiator box 3.

50 leaving two sections outside of the box at each the pipe is passed through the nipples 17, by 106 which the several sections of the radiator are joined.

In the form here shown they have inside ribs 18, primarily to engage a wrench for screwing them into place, and these ribs serve to center my pipe 15, and prevent v1- bration of the pipe such as otherwise might have a tendency to injure the threads where the threaded end of the pipe is made fast.

The pipe 15 length to reach and extend through the middle section of the radiator and it has a series of holes 19, formed through its walls, at top and sides, for the discharge of steam, and bottom holes 20 for the discharge of any Water that may accumulate. The total area' of the top and side holes should be at least equal to the cross sectional area of the pipe itself, and they should be opposite the hollow interior of the sections for maximum freedom of discharge.

By the above construction, steam delivered to the radiator is discharged into the middle sections where it will influence the tempera ture and humidity of the air coming in from out of doors and heat the room until the maximum capacity of these coils is reached. After that the unenclosed end coils heat up and furnish the additional radiation, but the outside air is always tempered before it is discharged into the room.

Having thus fully described my invention, what I claim as new and wish to secure by Letters Patent, is-

1. A radiator having a plurality of intermediate sections and other sections toward each end from the intermediate ones, nipples uniting the sections, a pipe supplying steam at one of the end sections, a valve in the pipe, and a pipe extension from the end of the first pipe passing through some of the nipples and discharging into sections remote from the outside section and spacing members centering the pipe in the nipples.

2. In combination with a radiator, a housing about a portion of the radiator open at one end, a fresh air duct discharging into the housing, and steam supply means discharging initially into said housed radiator portion.

3. In combination with a. radiator, a housing about a portion of the radiator openat one end, a fresh air duct discharging into the housing, and steam supply means discharging initially into said housed radiator portion, the unhoused portion of the radiator being connected to the housed portion to re ceive the flow of steam from said means after flowing through the housed portion.

In testimony whereof I aflix my signature.
